In the United States, almost all garbage disposals on the market are manufactured by a handful of companies; although, many are branded under different names. For example, out of the top ten highest rated models on the market, InSinkErator makes eight of them. Whirlpool and WasteKing are the other two most well-known brands in the U.S. There are a wide range of models to choose from, ranging from basic $50.00 models to models equipped with all of the latest bells and whistles that can cost as much as $600.00. In most cases, you get what you pay for in terms of quality. Here is a brief overview of the top brands in the U.S.
The mounting bracket for your new garbage disposer assembles by inserting the fiber gasket, back-up flange and mounting ring over the sink flange, in that order. Be sure to hold these three pieces in place while you insert the snap ring over the flange. It’s called a snap ring because you’ll hear it snap in place. Then firmly tighten the three mounting screws against the backup flange, being careful to tighten them evenly.
Installing a garbage disposal involves tapping into your home’s plumbing and electrical systems, and both systems need to be handled correctly to safely install your garbage disposal. Someone with a lot of experience can handle the job in 2 or 3 hours—or maybe even less. Attempting a garbage disposal installation without any training will likely take at least double the time required for a professional to install the garbage disposal.
If your garbage disposal is making a clicking or rattling sound, there may be some food particles that will not grind up inside. Remove power from disposer, reach into the sink hole with a pair of tongs and remove anything that is still down in the disposer. Test your disposer to be sure the noise is gone. If not continue troubleshooting your disposer issue (see below).
